Last week, back when it wasn’t raining non-stop in New York City, the real estate industry convened in 15 Union Square West’s Penthouse 11 for an art, architecture and design showcase, “TENTOONSTELLING,” by the Going Dutch Foundation. The event, hosted by Avenue magazine, developer Brack Capital Real Estate and building marketing team Brown Harris Stevens Select, was put on in conjunction with the 23rd annual International Contemporary Furniture Fair. In addition to the collection of Dutch artwork, design pieces and architecture models on display, the penthouse itself, designed by Vincente Wolf, was officially unveiled. The three-bedroom, three-and-a-half-bathroom spread is on the market for $10.7 million. Check out photos from the event in the slide show above. TRD
